火の玉ボーイ

Hino Tamao is a brash, big-hearted teen who arrives in Shonan searching for his deadbeat detective dad, earning himself the nickname "Fireball Boy" for his wild spirit. At the beach, he meets Momoko, a spunky girl who drags him into a whirlwind of high school chaos at Madaruya High. With guts to spare but little fighting skill, Tamao unleashes his secret weapon—superhuman “Hungry Power” that kicks in when his stomach growls—turning him into a force to be reckoned with.
